Shader Txt_Sp_Lit (Legacy)

The Txt_Sp_Lit shader has the following characteristics.

Explanation

• Applies lighting in real time to the object and multiplies it by texture, then added specular.

• Supports two lights, which are managed as omnidirectional without range.

Colors

• ColorD = Texture * (AmbientColor + NLuci (diffuse_term * DiffuseColor * LightColor))

• ColorS = NLuci (specular * LightColor)

• Final color = ColorD + ColorS

Code example for one light

This is an example of Txt_Sp_Lit shader with one light.

$Shader

{

szName = Txt_Sp_Lit

szLight = Omni001

}

Code example for two lights

This is an example of Txt_Sp_Lit shader with two lights.

$Shader

{

szName = Txt_Sp_Lit

szLight = Omni_Rossa

szLight = Omni_X

}

Input Data

Texture

• Material ® DiffuseMap

• UV Channel 1

• Alpha Channel. If the bAlphaTransparency or bSolidAlphaTransparency parameter is True, it impacts the pixel opacity.

• Must contain the Gloss Map values in the Alpha channel. The Gloss value scales the intensity of the specular. If the Gloss Map value is zero, the pixel will not have specular.

• The Gloss value is also used for reflectivity. A value of 1 indicates total reflection. This value is multiplied by fReflectivity.

Ambient Color

• Material ® AmbientColor

Diffuse Color

• Material ® DiffuseColor

Specular Color

• Material ® SpecularColor

Specular Intensity

• Material ® SpecularHilights ® SpecularLevel

• Increases the intensity and the size of the highlight.

Specular Glossiness

• Material ® SpecularHilights ® Glossiness

• Increasing this value increases the "shininess" of the object, so there will be a narrower highlight.

Light Color

• Light ® Color

• Color for every light.

Parameters

bObjectSpace

• Explicitly indicates whether this mesh will be exported to Object Space or World Space, regardless of export parameters.

• If this parameter is not present, the export parameters will be used, otherwise they will be overridden by this value.

• Default: The export parameters are used.

• Range: True / False.

fTransparency

• Transparency level of the mesh.

• Default: 0.0

• Range: [0..1] (1 = completely transparent)

bDoubleFace

• Duplicate the faces by flipping the verse.

• Default: False.

• Range: True / False.

bNoFaceCull

• Disables the face cull.

• Default: False.

• Range: True / False.

szAnimatedTexture

• Indicates that the texture will be animated using the specified Animated Texture ID.

• Default: Null.

szLight

• Name of the light that will illuminate the object. If not specified, the result will be unpredictable.
